ci: skip smart e2e ai selection for cherry-pick PRs targeting release branch

[chloeYue]

Description

This PR is to make release cherry-pick PRs execute the full smoke e2e instead of a reduced tag set chosen by ai.

On main, iterating quickly with a risk-scored subset is a reasonable tradeoff: we accept some residual risk in exchange for speed and we will catch more in follow-up PRs. A PR into release/* is effectively “this build is a candidate to ship.”
Smart selection saves CI time on high-volume main development. Release cherry-picks are low volume and high impact, and we cannot afford to merge cherry-pick that breaks the CI on release branch due to release urgency.

Note

Medium Risk
Changes CI behavior for release-branch PRs by bypassing AI selection and forcing full E2E runs, which can affect build time and which tests execute. Logic is localized to a single composite action and does not touch product code.

Overview
Updates the smart-e2e-selection composite action to detect PRs targeting release/* and skip the AI-based E2E test selection in that case.

For release/* PRs it now forces full E2E execution by setting force_run=true (and ai_confidence=100), and it avoids the checkout/dependency install steps used only for AI analysis; copy updates output/input descriptions to reflect the new behavior.

E2E Test Selection:
The only changed file is .github/actions/smart-e2e-selection/action.yml, which is a CI infrastructure file. The change adds a new code path to handle PRs targeting release/* branches: when detected, AI selection is skipped and force_run=true is set so the full E2E suite runs. This is purely a CI/workflow logic change with no modifications to app code, controllers, UI components, or any user-facing functionality.

What changed:

1. New step check-release-target detects release/* base branches
2. All AI analysis steps now skip when targeting a release branch
3. New elif branch in the analysis script sets FORCE_RUN=true and SHOULD_SKIP=true for release branch PRs
4. Updated descriptions/comments to reflect new behavior

Impact on app: None — this is purely CI infrastructure.

Why run any tests at all: Since this is a critical CI infrastructure file that controls the test selection pipeline itself, running a representative set of tests validates that the action still works correctly for the normal (non-release-branch) code path. A small but representative set of smoke tests across core areas is appropriate.

Why not run all tags: The app code is completely unchanged. Running all tags would be excessive for a CI description/logic-only change. The selected tags (SmokeAccounts, SmokeConfirmations, SmokeWalletPlatform, SmokeNetworkAbstractions) provide broad coverage across core wallet functionality to validate the pipeline works.

No performance tests needed: No app code, rendering, data loading, or performance-sensitive paths were modified.

Performance Test Selection:
No app code was modified. The change is purely to CI/workflow infrastructure (the smart E2E selection action). No UI components, data loading, state management, or performance-sensitive code paths were touched. Performance tests are not warranted.
